Poly(2-fluoro-1,4-phenylenevinylene), PFPV, and its copolymers have been synthesized via water soluble precursor route and their electrical and optical propreties were measured. It seems that electron-withdrawing fluorine substituent on phenylene ring increases the band-gap of PFPV and it affects electrical and optical properties. The conductivity values of FeCl3-doped drawn polymer films ranged from 10-1 to 101 Scm-1 depending on their composition, and were 10 times larger than those of undrawn ones. The χ(3) value for undrawn PFPV, using THG technique at 1907nm fundamental wavelength, was 4.76x10-12 esu.
